In this blog post, we’ll explore the importance and effectiveness of “communication” as a practical solution for preventing free-riding in group projects.
Group activities, where members collaborate to solve tasks, often face various challenges. The main reasons group projects become difficult are a lack of communication or conflicts among group members, which lead to poor role allocation, and members failing to properly fulfill their assigned roles. In particular, a lack of communication can cause problems right from the early stages of the project. If individual roles are not clearly defined or schedules are not properly coordinated, group members may experience confusion. This not only slows down the progress of the work but also increases the likelihood of unnecessary conflict. The behavior of group members failing to perform their assigned roles—known as “free-riding”—is primarily caused by a lack of responsibility. Achieving the results a group is expected to produce requires a certain amount of effort. However, the more self-serving behaviors—such as “free-riding”—occur in group activities, the greater the workload assigned to responsible members, resulting in a disproportionate burden on the diligent few.
If situations where a small number of responsible members must handle a large volume of tasks recur in group activities, the psychological burden on those members gradually increases. This can lead to a decline in the quality of the work and may also worsen relationships among members. It is ironic that those who complete their assigned tasks are evaluated on the same level as those who “turn a blind eye” and free-ride. To prevent such unfair treatment, many groups have established systems to deter free-riding. While there are punitive methods to prevent free-riding—such as completely excluding free-riders from the team roster or requiring group members to submit mutual evaluation forms along with their work—I do not consider these the best approach, as they can have side effects like making members view each other as targets for surveillance or potential free-riders. While these methods may be effective in the short term, they risk undermining trust and teamwork among members.
In my view, the best approach is to prevent free-riding through regular communication among members. This method is based on mutual trust and focuses on encouraging each member to take personal responsibility. By sharing thoughts and progress through regular dialogue, members naturally feel accountable to one another, thereby reducing the likelihood of free-riding. The power of communication is greater than one might think, and this has already been confirmed in various groups.
How can we prevent free-riders from emerging through communication among members alone? Reaching a consensus through dialogue goes beyond a simple exchange of opinions; it is a process of understanding and reconciling each other’s positions. People communicate with others through conversation. Diplomacy—the foreign relations between nations—is also a form of communication. Since communication plays a vital role in nearly every field of life, it can also be used as a method to prevent free-riding. For example, numerous studies show that smooth communication within teams directly impacts work performance in corporate settings. These examples clearly demonstrate how crucial communication is to an organization’s success.
The “Communication Hypothesis” includes the idea that members of society come to understand which behaviors are socially desirable through communication, and that they develop a sense of obligation to engage in socially beneficial actions. Furthermore, this hypothesis encompasses the notion that trust among members increases and that a sense of collective identity emerges, leading to heightened responsibility. Trust and responsibility are crucial elements that form the foundation of effective cooperation.
When these elements are in place, conflicts among members decrease, and tasks can be carried out more efficiently. According to the Commons Game experiment, which confirmed the validity of the communication hypothesis, the tragedy of the commons can be prevented if members have sufficient opportunities for communication. The tragedy of the commons refers to a phenomenon in which members of a community use shared resources beyond sustainable limits, causing the resources to diminish or be depleted, resulting in losses for all members.
This experiment consisted of four trials that introduced elements such as retaliatory measures and communication among members to prevent the tragedy of the commons. A total of four experiments were conducted: Experiment 1, which introduced a fine system as a retaliatory measure; Experiment 2, which merely attempted to introduce such a system; Experiment 3, which added a one-time communication session among members; and Experiment 4, which added regular communication.
The results showed that in Experiments 2 and 3, the use of public goods decreased only immediately after the introduction of the fine system and immediately after communication, respectively, and over time, participants’ use of public goods returned to previous levels. In contrast, in Experiments 1 and 4, the use of public goods decreased and remained at that level. The experiments confirmed that regular communication can elicit altruistic behavior and sustain it. While introducing a fine system is as effective as communication, considering factors such as the resistance it may cause among members—given that the introduction of a punitive system itself can be off-putting—it is evident that increasing communication among members is more effective than other measures in terms of team cohesion and trust among participants.
These experimental results can be applied to various organizations. The importance of communication is significant, ranging from small organizations such as companies or clubs to national-level policies. If regular meetings or consultations do not proceed smoothly, conflict among members is inevitable.
The finding that communication is effective can be applied to methods for preventing free-riding in group activities. If periodic communication is introduced in group activities as a method to reduce free-riders, it can lead to outcomes consistent with communication hypotheses: members will develop a sense of obligation to act in the group’s best interest, trust among members will increase, and a sense of collective identity will emerge. Consequently, all members will act altruistically, resulting in the elimination of free-riders in group assignments.
As such, we can see that communication theories can be effectively used to prevent free-riding. Preventing free-riding is intended to avoid causing harm to others. However, this is not the only reason why one should not free-ride. There are reasons not to free-ride not only for the sake of others but also for one’s own sake. From a broader perspective, the question of why one should not free-ride is related to why one should live righteously.
